CULTIVATO R.

SPECIFICATION forming part of Letters Patent No. 331,738, dated December1, 1885.

Application filed September 9; 1885. Serial No. 176,623. (No model.)

To all whom it may concern:

Be it known that I, HARLOW G. STAHL, a citizen of the United States,residing at Fremont, in the county of Sandusky and State of Ohio, haveinvented certain new and useful Improvements in Cultivators; and I dohere by declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

This invention relates to cultivators of the kind as shown in the patentto M. Bruner, J r., No. 100,720, dated March 15,1870; and it consists inthe detailed construction and combination of parts, hereinafter fullydescribed and claimed, by which the construction and working of thecultivator are improved and facilitated.

In the drawings, Figure I is a plan View of thecultivator, lookingdownward from above. Fig. II is a side view of the cultivator with oneof thewheels removed. Fig. 111 is a rear view of the machine. Fig. IV isa detail plan view of larger size, showing the attachment of a mainstandard-rod, a seat-bar, and the axle with the frame of the machine.Fig. V is a rear view of the same. Fig. VI is a side view of the same.Fig. VII is a detail end view of one of the steps, showing the plow-beamin cross-section. Fig. VIII is a side view of the step.

Similar letters of reference indicate corre sponding parts in all thefigures.

The framing of the cultivator consists of two side bars, A, and a centerbar, A. These bars are secured to the axle by clips, and to one anotherby the cross-piece a. The side bars, A, are also secured to the lowerpart of the axle by the braces :1

Bare the plow-beams, provided with curved draw-bars G at their frontends, which are pivoted to the side bars, A, in any convenient manner.Each plow-beam consists of two diverging parts, which are united towardthe front, where they are joined to the draw-bar.

D are the cultivator-standards, or teeth,

which may be secured to the plow-beams in any convenient manner.

E are the main standards, pivoted to the plow-beams at their lower ends,and having their upper ends pivoted in and supported by the mainstandard-rods F. A chain, 6, is provided which couples the mainstandards together and prevents the plow-beams from spreading too farapart. Each main standard is provided with a bolt, e, at the bottom,which also passes through the diverging parts of the plow-beam, betweenwhich the said main standard is placed, with a hole, 6, near the top endfor engaging with the loop of the rod F, and with a collar, 6 providedwith a projecting hook, e, at the extreme top for the attachment of thespring-chain.

G are the spring-chains, each of which is provided with a spring, Thesechains connect the tops of the main standards with the side bars, A, infront of the rods F, and prevent the cultivatonteeth from penetratingtoo far under the surface of the ground. The springchains also sustainthe teeth in a manner pleasant tothe operator and team, greatly relievethe draft, make the side movement of the beams much easier in avoidingirregular hills, and enable the operator to make the teeth penetratedeeper than common, where necessary in passing over dead-furrows, bypressing on the step, and thus distending the spring.

H are the lug-brackets bolted to the side bars, A, for'sccuring theouter ends of the rods F. The inner ends of rods F are secured to thelug-bracket H, which is bolted to the center bar, A. The ends of therods F are flattened, and are provided with an elongated hole, f,through each of them. The brackets H and H are provided with lugs h,circular in form, projecting from them, for the attachment of the mainstandard-rod ends. Each log it has on one side close to the end of it aprojection, h, which prevents the said rods F from coming unfastenedwhen the cultivator is at work.

In order to attach the rods F to the lugbrackets, the machine must betilted up, or otherwise placed in such a position that the elongatedholes f may be slipped over the projections h of the lugs. It will benoticed that the brackets H have one lug, and that the center bracket,H, has two similar lugs, to which the ends of the rods F may attach. Thetwo looped rods F, and the main standards to which they are attached,are therefore kept perfectly distinct, and the two halves of thecultivator can be moved in all directions independently of one another.

I is a tool-box, which may conveniently be attached to the center bar,A.

J is the seat for the driver, securely fastened upon the. spring 9', andsuspended from the ends of the two seat-bars K by means of the pins j,which project upward from the collars j secured on the ends of the saidseat-bars, and which pins engage with any of a series of holes, 9' inthe seat-spring. The seat-bars K are made removable from the side bars,A, to which they are connected, and can be drawn back and forth, asfound convenient, so that the seat J may be placed nearer to or fartheraway from the main standards E. The front ends of the seat-bars K aremade rectangular in section corresponding with the side bars, A.

k are loops through which the ends of the seat-bars pass. These loopspass from the top and bottom of the side bars, A, round the outside ofthe seat-bars, and the same bolt by which these loops are attached tothe side bars may conveniently serve as an attachment for thespring-chains, and also secure the ends of the cross-piece a and thebraces a The seatbars K are further supported by the troughshaped pieceswhich are clamped in between the axle and the side bars, A, and havetheir flanges uppermost to retain the seat-bars in position laterally.

L is the axle of the cultivator, firmly secured to the bars A A of theframe by straps land suitable bolts which pass through the said bars andalso secure the lug-brackets to them. The ends of the axle are bentdownward and outward to form journals for the wheels M, which may be ofany approved construction.

In order to overcome the tendency of the seat-bars to draw inward theside bars, A, when the weight of the driver is on the seat, the axle hastwo creases or depressions, Z, formed in it while being bent. The strapsZ, which secure the axle to the side bars, A, are placed in thesedepressions, which correspond with them in width, and the side bars arethereby held rigidly in position.

N are the steps, each of which has holes n passing through it. Theseholes are placed in the middle of the width of the step, and far enoughdown from the top to come opposite to or a little below the middle ofthe plowbeam. Each step is curved on one side, so as to form a shoulder,n, which presses against the under side of the plow-beam. The sides ofthe steps having the holes n in them are placed between the divergingparts of the plow-beams and the lower ends of the main standard. Thebolts 6 pass through the said steps, plow-beams, and main standards, andthe shoulders n, and prevent the steps from rocking.

R is a double-tree attached to the center bar, A, by means of the bolt1".

r is a distance-block placed between the double-tree and the center bar.

0" is the hammer-strap for supporting the lower end of bolt r.

S are the trace-carriers attached to the ends of the double-tree bybolts .9 and straps 8. Each trace-carrier is provided with suitablehooks, by which the traces are fastened to it. The object of this formof construction is to reduce the height of the traces above the groundto a convenient level, so that the inner traces may be kept fromentanglement with the attachments by which the draw-bars are secured tothe side bars, and so that all unnecessary weight may be taken 0d thenecks of the horses.

Having thus described myinvention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a cultivator, the combination of the plow-beams,the mainstandards, the looped rods F, provided with flat ends having elongatedholes in them, the lug-brackets H, and the lug-bracket H, so that theplow-beams can be worked independently of each other, substantially asdescribed and shown.

2. In a cultivator, the combination of the plow-beams, the mainstandards provided with collars e having hooks e projecting therefrom,the main standard-rods F, pivoted to the framing of the cultivator, theside bars, A, and the spring-chains G, having springs g, for connectingthe tops of the main standards with the said side bars and limiting thedownward movement of the cultivator-teeth, sub stantially as describedand shown.

3. In a cultivator, the combination of the removable and adjustableseat-bars K, the spring-seat J, attached to the rear ends of the saidseat-bars, the loops in, bolted to the side bars, and the trough-shapedpieces k, clamped between the said side bars and the axle, substantiallyas described and shown.

4:. In a cultivator, the combination of the steps N, provided with thebolt-holes n and shoulders at, the plow-beams B, main standards E, mainstandard-rods F, pivoted to the framing, and the bolts 6, substantiallyas and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
